This is so fun! I can't believe that I didn't know this was a thing!
This scene is from The Lion King, and the words that Scar says to Mufasa were modified to say instead of "Long live the King", to "Thou shall fall with gravity!" which shows that gravity will take Mufasa down.
Mufasa was pushed off a cliff, but to his advantage, he decided to tie a vine to his leg before he fell with his quick thinking.
Mufasa's vine that saved him from crashing into the water was what we now know as a "bungee cord", which is a device that after falling a certain distance, prevents you from hitting the ground, and here Mufasa is bobbing up and down with the power of Newtons theory of gravity.
